    Replace all occurrences of $ with $$ in vCenter input values

    - OpenStack services may reference to previously defined variable in
      configuration files using $ (dollar sign), e.g. 'metadata_host =
      $my_ip'. Interpolation can be avoided by using $$. Passwords often
      contain metachars and $ is one of them. We must replace all $
      occurrences with $$, otherwise service will fail to start because it
      cannot interpolate non-existing variable.
    - add static method escape_dollar() to VMwareDeploymentSerializerMixin
      class that implements conversion
    - also handle username and regular expression that is used for datastore
      search
    - provide input values with '$' in test fixture vmware_attributes.json
    - modify integration test
